the first and ninth the shortest. The longer appendnges liave the hairs 

 parted down the middle, those on the anterior half pointing to the 

 head, and those on the posterior half pointing to the tail. The hairs on 

 the short appendages are not so parted. At the base of each appen- 

 dage, except those of the ninth pair, is a tuft of hairs so arranged as to 

 point in all directions from the centerof the tuft, and leave a middle, 

 longitudinal groove, extending the entire length of the dorsal surface. 

 The third and fifth pair§ of appendages are so twisted, as to exhibit 

 their under surfaces at the outer third, and to make the tips point up- 

 ward and forward. 



The seventh pair is not twisted, and points obliquely backward, ex- 

 tending one half its length beyond the caudal extremity of the insect. 

 Lateral surfaces arched above, straight beneath, witli a row of light 

 brown tufts of hair above each spiracle. Under surface and lateral 

 surfaces below the stigmata orange yellow, under surface darker at the 

 lateral margins. Head and mouth parts jet black and shining, and en- 

 tirely concealed under the enormous hood, and this under the first and 

 second pairs of appendages. Length, on dorsal surface j\ inch. 

 Breadth, exclusive of appendages, y\ inch. Oct. 9, 1874. Ulmus 

 atnericanus. Master Ernest Baker. One specimen. 



Remarks. Tliis remarkable insect bears resemblance to L. hjalinus, 

 Walsh, and L. tetradadylns of the same author, given in Proceedings 

 Boston Society Natural History, Vol. IX. Feb. 1864. While it has 

 characters in common with these, as given in the paper above alluded to, 

 it is double the size of the first, and much larger than the second. 

 The tufts of radiating hairs, forming two longitudinal rows along tlie 

 dorsal surfiice, are a notable feature, and could not have escaped the 

 eye of so acute an observer as Mr. Walsh. He does not mention the 

 dark, velvet browai, under surface of the appendages, which is a very 

 striking feature. In color, and in many other respects, it accords well 

 with this description of -L. /ii/a/iuHS, and in size with L. tetm-hctiilii:'. 

 The larva is sluggish, and exceptionally voracious. If uudescribed, it 

 may be called L. nondemrlptus.
